The original user control code in the accpected answer in this link :

not sure why it's crashing when trying to updating the SaveState it self.

CodePudding user response：

When you write

SaveState = value;

you call the setter.

When you do so in the setter's code, this causes infinite recursion - you assign to SaveState in the setter, which calls the setter, which assigns to SaveState, which calls the setter, which assigns to SaveState, which calls the setter, and so forth forever, which is causing the IDE to crash.

The moral of the story: NEVER assign to the property inside the setter; ALWAYS assign to the backing field instead.
